EOI in getting SPI going on the RPi5 solved read First post for updated info

Yeah saw that, but to tell you the truth lost interest.
Got burnt out providing answers and on the rare occasions I had one getting SFA in return.
Tho the tipping point was the when I had a fix for the ipv6 thing and the missing icons on the lower panel.
Had some members pulling from the wrong repo and whinging that it didn’t work. Others saying the sources I was using were out of date and you couldn’t build a Debian iso in Mint. And a complete lack of anyone willing to help and. Even from the few locals that have my number and call me for help.
So I’ve quietly said fuck it.

There’s much smarter, patient and personable people around.

RANT, skip freely:
Welcome to the club!
I was OK with wasting hours to have any use from RPI3B as it was 35$ (65 Euro here), cheap enough to warrant a bit of tinkering, it was slow sluggish, cr@ppy,slow USB, even slower LAN, but it worked
RPI4 came out and the price went sky high, so the price to fun ratio went out the door.
Then came RPI5 and it's seven hardware versions in the first months and a price tag worthy of a kingdom, so i am out.
I blame people who buy it to a certain point, i absolutely blame youtubers in 3D printing for insisting you need RPI to run Klipper, a 30$ used SFF PC is much, much better at Klipper and does not stop mid print when doing timelapses, ruining time and material and nerves.
By now, my list of banned stuff has gotten really, really long, RPI is there, together with Microshaft, Adobe, Intel, BMW, MSI, etc, etc...
Not only RPI, any SBC lately is over 150$, add a screen and it gets to 300$ easily, i can buy new laptops for 200-250 Euro on sale here with 1 year warranty, they are cr@ppy laptops but magnificent RPI alternative, with day long battery life when screen if off!

SPI is now supported on the RPI5 so 7C80,7C81,7I90 will work with the RPI5.
Still need to add a force-8-bit option to Mesaflash as the kernel driver doesn't
support 32 bit transfers but seems to report that it can.

 

Sounds great Pete.
Will give it shot once the heat backs off.

Just got an RT enabled kernel loaded on my fresh pi5, any docs you could point me to for the spi stuff (unless it's just running current kernel) and the mesaflash option? I will be connecting to a 7c80, but am doing all the prep work outside of the enclosure (mainly so I can clone the SD card once its base config is done.

Ok this thread was primarily for the development of a Linuxcnc spi driver for the RPi5.
This as been done, but you will need to build either 2.9 or master from source.
There is a more recent thread discussing this.
Apart from the new driver everything that applies to RPi 4 and either the 7c81 or 7c80 is relevant.
There is a quite large thread on the 7c81 that you may want to read, the 7c80 manual should have information on using mesa flash.
Setup and mesa flash was not the point of this thread . Now that a driver has been developed this thread is pretty much moot.
